    Assuming that the distribution of sequences of characters is uniform.
    But it's not! As soon as you start using this encoding somewhere,
    the probability of appearing of this sequence raises dramatically.
    If you convert UTF-8 -> UTF-32 using modified rules, and UTF-32 -> UTF-8
    using standard rules, then you get this sequence without waiting
    2^340 years.
